There are several main reasons for the heat inside the earth. Keep in mind, though, that scientists really don't agree on how hot the core of the earth might be. 3000C? 4000C? 7000C? One source is radioactive decay. Elements including Uranium and Radium are constantly decaying and releasing energy. A second source is simply the result of Earth's formation -- billions and billions of tons of rocks and metal and gasses compressing downward release a lot of heat. The last reason is tidal stress. As the moon goes around earth, its gravitational field makes shifts in earth's crust and mantle. These shifts produce heat. Some scientists think that these models still don't adequately explain the continued tremendous heat in Earth's core, but these ideas are the best we have for now.

∙ 9y agoThe two main sources of heat inside the earth are residual heat and radioactive decay. They both occur within the depths of the earth.

∙ 9y agoThe internal heat of the Earth is a result of two things. It is a result of gravitational compression mostly, and the decay of radioactive isotopes.

What are the two sources of energy in the earths system?
The sun's rays and wind.
By what two methods does geothermal heat get to the earths surface?
by making babies
What are the primary sources of heat that drive the geologic processes on Earth?
The flow of energy from Earth's interior to its surface comes mainly from three soucres: early impacts, gravitational energy, and the ongoing decay of radioactive elements. The sun is also a factor.
What two types of rock provided evidence of the composition of Earths interior?
What two types of rock provided evidence of the composition of Earth'sinterior
What are the two principal sources of heat in the Earth Which has a greater contribution tosurface heat flux?
The two principal sources of heat are the Sun and the Earth itself via geothermal heat. The sun's heat will vary more than geothermal, and therefore contribute more to flux.
The two fundamental sources of energy that drive earths systems are?
Two sources are sun and Earth's interior
What is the main source of the earths interior heat?
the mantle plume There are two source of heat in the earth's interior. The main two sources are fire and breathing heat.
What are the two sources of that power earths energy?
The sun and the earth's interior are the two sources of energy that power earth's systems.
What are the two source of heat in the earths interior?
sunlight and meteor impacts
What are two sources of energy that power earths system?
The sun and the earth's interior are the two sources of energy that power earth's systems.
What is the main source of heat in Earth's interior?
the mantle plume There are two source of heat in the earth's interior. The main two sources are fire and breathing heat.
What are the sources of energy that power the earths systems?
The sun and the earth's interior are the two sources of energy that power earth's systems.
What are the two source of energy that power the earths system?
The sun and the earth's interior are the two sources of energy that power earth's systems.
How is heat from earths interior transferred to earths surface by convections?
Beneath the surface of the earth temperature remains the same. Within the Earth, irregular convection cells within the mantle transfer heat from the core to the surface of the planet. Volcanoes and earthquakes are two examples of heat transferring from the interior to the surface.
Which two energy sources are not directly tied to solar energy?
Tidal energy, and the heat from the interior of Earth.
What are the two main sources of energy in earths spheres?
The two sources of energy are the sun and energy from the Earth's Interior.
What is the source of the energy that powers the earths system?
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.
